Abstract
The invention provides a microphone device. The microphone device comprises a cavity communicated with the outside, a duct communicated with the cavity, and a microphone connected with one end of the duct far from the cavity, wherein the microphone is provided with a sound inlet hole; and a chamber for communicating the duct and the sound inlet hole is arranged between the microphone and the duct. The microphone device has good wind noise resistance, and the sensitivity and the acoustical property of the microphone device are greatly improved.
Description
[technical field]
The present invention relates to a kind of microphone apparatus, relate in particular to the cavity that microphone is in communication with the outside.
[background technology]
Development along with wireless telecommunications, Global Mobile Phone Users is more and more, the user not only is satisfied with conversation to the requirement of mobile phone, and want high-quality communication effect can be provided, especially at present the development of mobile multimedia technology, the speech quality of mobile phone becomes more important, and the microphone of mobile phone is as the voice pick device of mobile phone, and its design quality directly influences speech quality.
There is the problem to ambient noise restraint difference in present microphone, when people externally use mobile phone calling in the environment, can be subjected to the interference and the influence of other external agencys such as wind-force, and making originally clearly, speech becomes noisy, interrupted.Not only reduce the acoustical behavior of microphone, also involve simultaneously and microphone is installed also is affected in wherein mobile phone.Therefore, for the foregoing reasons, the present invention is necessary to provide a kind of new microphone apparatus to solve the problems referred to above.
[summary of the invention]
The technical problem that the present invention need solve is to provide a kind of and can effectively reduces wind and make an uproar, the microphone apparatus that self sensitivity is improved greatly.
The present invention is achieved by the following technical solutions:
A kind of microphone apparatus, wherein, the pipeline that this microphone apparatus comprises the cavity that is in communication with the outside, communicate with cavity, with the microphone that pipeline links to each other away from cavity one end, described microphone is provided with sound hole, also is provided with the chamber of connecting pipe and sound hole between described microphone and the pipeline.
As a kind of improvement of the present invention, described microphone apparatus also comprises the shell of accommodating microphone, pipeline and chamber, the first surface that described cavity runs through shell reaches and the first surface opposing second surface, described cavity is provided with the sidewall that connects first surface and second surface, and described pipeline links to each other with sidewall.
As a kind of improvement of the present invention, described pipeline is positioned at the middle section position of described sidewall.
As a kind of improvement of the present invention, described pipeline is positioned at the position of described sidewall near described first surface.
As a kind of improvement of the present invention, described pipeline is positioned at the position of described sidewall near described second surface.
As a kind of improvement of the present invention, the diameter of described pipeline is less than or equal to the diameter of microphone.
As a kind of improvement of the present invention, the diameter of described chamber and the equal diameters of microphone.
As a kind of improvement of the present invention, be respectively equipped with sponge in described cavity and the described chamber.
As a kind of improvement of the present invention, be provided with sponge in the described pipeline.
The present invention has the following advantages: this microphone apparatus can improve the sensitivity of microphone greatly, the acoustic feature of microphone is had greatly promote; Simultaneously, in certain frequency range, this microphone apparatus also has certain directive property, and the noise of surrounding enviroment is had good restraining power, is beneficial to the raising of microphone signal to noise ratio.
